I took the FFT of a signal that was taken at non constant time period (T), but at a sampling frequency(Fs) of 6.5 hz. Can I take the FFT of a signal with non constant T, and does it mean anything? Please see attachment.

Ps. I used Matlabs, FFT command, which i think uses the Cooley–Tukey FFT algorithm
